Was thinking of a Rengar Vs Kha'zix game mode and here's the idea that i got (not khas vs rengos)
The most beloved rivalry in league of legends lore is kha vs rengar and who doesn't like the rivalry of two one of the most fearsome badass beast-hunting monsters.
As a fan of those two i thought a game mode themed around them would be really nice , not 5 khas vs 5 rengos summoners' rift.. But instead something like ascension.
The idea i came up with is like blue team is kha'zix team and red team is rengar's team , kha'zix wants to reach some sort of a thing to finish his super evolved ultimate form , but rengar stops him from doing that, so he is forced to defeat him and then procceeds to his goal.
Pretty much like attack/Defend game mode like nexus siege however, both teams will have some sort of a herald-like ( Or like Xerath in ascension but walking )
and
, Kha'zix' team will help him kill rengar reach to his target , while rengar and his team will try to stop them on a one lane map.
Winning conditions :
The winner team is the first one to kill
